Abstract
A split-level seating device for elevating and mounting alternate rows of seats for aircraft, surface transportation and for stationary applications, as a means to gain greater seating capacity and to attain a high level of comfort for every sitter, by pre-empting otherwise unutilized or inefficient spatial displacement within such vehicles, to enable every sitter a lower seating position and every sitter to raise the legs at or above the level of the torso. A modular structure raises every other row of seats with their corresponding cross-aisle walkways at a sufficient height to provide legroom for floor level sitter, said module incorporating a legrest extension for upper level sitter, including the means for affixing state-of-the-art safety, sanitary and conveniency devices, such as safety crash-absorbing air bags and high-security kevlar lining, oxygen dispensers, purge vents and ultra-violet light outlets to cleanse the environment, moveable and adjustable footrests, eating-writing surfaces, and audio-visual entertainment and communications devices. The manner following convention of mounting arrays of massed seats at floor level is improved upon by elevating alternate rows of seats by means of said modular devices, all seats, both floor and split-level, being accessed from the same floor surface.
Claims
AMENDED CLAIMS
[received b> the International Bureau on 10 April 1997 (10 04 97), original claims 1-1 replaced by new claims 1-4 0 pages)]
"/f A unitized split-level seating device for expedited installation, pitch adjustment and removal in transportation interiors and open spaces with a plurality of unidirectional seats . with fully reclining or sleeping mode seatback arrangement, such as in aircraft, buses trains and the like and comprising a torsionally rigid seat-elevating pedestal structure including the substantially integral combination of plural laterally spaced and longitudinally oriented beams, cross rails, corner posts and panels defining the lateral boundaries of said structure, means extending between first laterally opposite pairs of longitudinal beams into a plurality of mutually exclusive, parallel and immediate laterally adjacent passenger or individual seating sections, means of displaceably supporting each of said seats between said corner posts whereby each seat may be at least partially displaced vertically from the floor surface, means of displaceably supporting cross-aisle walkway between said corner posts and beams whereby each seat is served by said walkway which is partially disposed at least at a lower level than the said seats but at least partial I v displaced vertically from said floor surface, means for upwardly extending forward posts connecting to said walkway to mainframe intermediate member supporting a panel extending from said floor surface substantially vertically above said floor surface at least partially vertically above said walkway and at least partially vertically above bench level of said seat, said panel connecting to a sloping portion supporting a legrest extension, said sloping portion extending upwardly and forwardly and connecting to a vertical panel terminating at overhead structure of vehicle or compartment, said sloping portion at least vertically clearing upper seatback headrest portion of floor level seat, means alternatively linking said walkway with main frame supporting a panel which is disposed at least substantially vertically from said floor surface and at
13
least vertically above said walkway and extending to the overhead structure of vehicle or compartment "2 A unitized split-level seating device for expedited installation, pitch adjustment and removal in transportation interiors and open spaces with a plurality of seats with fully reclining or sleeping mode seatback arrangement, such as in aircraft, buses, trains and the like and comprising a torsionally rigid seat-elevating pedestal structure including the substantially integral combination of plural laterally spaced and longitudinally oriented beams, cross rails, comer posts and panels defining the lateral boundaries of said structure, means extending between first laterally opposite pairs of longitudinal beams into a plurality of mutually exclusive, parallel and immediately laterally adjacent passenger or individual seating sections, means of displaceably supporting each of said seats between said co er posts whereby one post is connected to horizontal intermediate frame supporting said seat, where said seat may be at least partially displaced vertically from said floor surface, said seat at least vertically clearing the seatback headrest portion of floor level seat, means of displaceably supporting cross-aisle walkway between said co er posts and beams whereby each seat is served by said walkway which is partially disposed at least at a lower level than the said seats but at least partially displaced vertically from said floor surface, means of upwardly extending co er post connecting to said walkway and supporting a panel, said panel starting from the level of said walkway extending substantially vertically upward at least partially above seat bench level of said seat, connecting to a legrest extension, said legrest extension sloping upwardly and forwardly and connecting to a substantially vertical panel terminating at overhead structure of vehicle or compartment "3 A unitized split-level seating device for expedited installation, pitch adjustment and removal in transportation interiors and open spaces with fully reclining or sleeping mode seatback arrangement, such as in aircraft, buses and the like as in claim 4, further comprising.
H
ancillary means of displaceably attaching on top and bottom of said split-level device structure for anchoring or movably suspending along longitudinal rails said structure by rollers, or permit simultaneously rolling along longitudinal rails on said floor structure by casters "4 A unitized split-level seating device for expedited installation, pitch adjustment and removal in transportation interiors and open spaces with a plurality of seats with fully reclining or sleeping mode seatback arrangement, such as in aircraft, buses, trains and the like as in claim 5. further comprising ancillary means of displaceably attaching safety airbags fore and aft for floor level seat, safety airbags fore and aft for split-level seat, writing-eating surfaces, footrest, ottoman, infrared lamp outlets air purging vents, luggage compartments, including but not limited to oxygen dispensing taps and audio-visual communications and entertainment devices "

STATEMENT UNDER ARTICLE 19
The amendments involve the cancellation of previously submitted claims 1 to 3 which had been disallowed by the U S. Patent Office on the grounds that claims 1-3 failed to define the invention in the manner required by U S C S 1 12, second paragraph, being narrative in form and replete with indefinite and functional or operational language, requiring that the structure which goes to make up the device must be clearly and positively specified It must be organized and correlated in such a manner as to present a complete operative device Claim 1 and 3 were rejected under 35 U S C S 102(b) as being anticipated as understood by Candhn (2,977,898), and Claim 2 and 3 were rejected under 35 U S C S 102(b) as being anticipated as understood by Jergenson (2,608,366) Accordingly, the first submitted claims were canceled and a replacement set of four (4) claims were submitted to the U S Patent Office which are the same claims being submitted herewith to the PCT, verbatim. The replacement claims have no reciprocal effect whatsoever on the descriptions and drawings as originally submitted, and the same may stand as identically to the said original descriptions and drawings without any change
